本轮已完成对 TNF / IL-6 的低优先级对照轴排除：
- 找到原始证据 PMID 33260150：TNFα 阻断（etanercept）在 aging mice 中可防止 sarcopenia，并延长 survival；
- 但效应主要集中在骨骼肌与局部炎症回路，白细胞募集影响有限，更像“组织/病理特异因子”；
- 对 IL-6 的检索没有找到同等级别的直接延寿原始证据；
- 因此二者都不应升级为全身性的 universal longevity bottleneck，只能作为 inflammaging 的对照轴。
我还把这一判断沉淀成了长期记忆：
- `TNF/IL-6 are context-specific inflammaging mediators, not universal longevity bottlenecks`
